CIRCULATING sAsmuaNna.

Applicationfiled November 3, 1324: Serial, No. 747,541.

To all'whom it may concern:

Be it known that we, JAY M. AXTELL and FREDERICK G. VON Hormv, citizensof the United States, residing at Fort \Vorth, in the county of Tarrantand State of Texas, have invented certain new and useful Improvements inCirculating Gas Burners, of which the following is a specification.

Our invention relates to gas burners and more particularly tocirculating gas burners; and the object is to provide gas burners whichare provided with a plurality of jets and to provide means for obtaininguniform pressure for all of the jets and to provide means for causing acirculation of the gas to obtain such pressure. The object is to providegas burners for general heating purposes. Other objects and advantageswill be fully explained in the following description and the inventionwill be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of thisapplication.

Fig. 1 is a plan view'of the burner with parts thereof shown in section.Fig. 2 is a transverse section, taken on the line 22 of Fig. 1. Fig. 3is a side elevation of the burner. Fig. 4 is a plan. view of a burnerwithout arches and without a pilot burner.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The improved burner is provided with a receiving nozzle 1 and sidemembers 2 and 3 and a circulating member 4. A plurality of arches 5 aretapped into the members 2 and 3 and these arches are provided withdischarge burner nozzles or apertures 6. The arches 5 are adjusted onthe members 2 and 3 by unions 7 which engage the arches 5 and arescrewed into the plugs 8. v

The gas is made to circulate by means of the member 4. The gas followsthe direction of the arrow heads. Gas enters the nozzle 1 and strikes adivider or battle 9 which directs the gas to the members 2 and 3. Thegas passes through these members and feeds the burner arches 5 andpasses on to the opposite ends of the members 2 and 3. The passing gaswillstrike another baflie 10 and be directed thereby to the circulatingmember 4. The gas will pass on and strike the baflies 11 and 12 and bedirected back through the members 2 and 3. The gas which is passing to.the members .2 and. 3 from the nozzle 1 will tend to create suctionwhich will draw'the gas from member 4 past the battle plates 11 and 12.In this manner the pressure is maintained uniform throughout the feedpipes 2 and 3.

Provision is made for a pilot burner. A pipe 13 is extended along thepipe 4 and then up and provided with a burner nozzle 14. Gas is suppliedfor the pilot burner and this burner will cause the gas to ignite in allthe other burners. Two of the arches 5 are shown in section in Fig. 1.

The burner illustrated in Fig. 4 is not provided with arches 5, but ithas burner nozzles 6 directly in the pipes 2 and 3. Various otherchanges in the sizes, proportions, construction and arrangement of theseveral parts may be. made without departing from our invention.

The form of burner shown in Fig. 4 may be inverted for broiling andother purposes.

What we claim, is, A p 1. A gas burner comprising gas feed members,burner arches-connected to said feed members, a circulating membercommunicating at both ends with said feed members, means at thereceiving ends of said gas feed members for directing gas into saidmembers, means at the discharge end of said feed members for directinggas into said circulating member, and means at the discharge end of saidcirculating member for dividing the gas and directing the same into saidfeed members. I 2. A gas burner comprising gas feed members and acirculating member communicating with said feed members: at both ends,burner nozzles operatively connected to said feed members,,means forsupplying gas to said feed members, means for dividing the 7 gas to saidburner, and burner arches connected to said feed members from one feedmember to the other.

l. A gas burner comprising gas feed members and a circulating membercommunicating with said feed members at both ends, means for directinggas from the supply source through said feed members and for causing gasto pass from said feed members 10 to said circulating member, means forcausing gas to pass from .said circulating member to said feed members,burner nozzles operatively connected to said feed members, and a pilotburner operatively connected to said burner.

In testimony whereof We set our hands this 27th day of October, 1924.
